To all of those who have worked the front heatsink and paste. How tight did you go when re-attaching? I normally wouldn't be paranoid about things like this but it seems like they weren't that tight from the factory at all. Certainly don't want to crush any SMCs.
Tighten until resistance?

You are both a danger and a joke at the expense of your own EGO? why not post the rest of the page FROM THE AS5 SITE?  Not Electrically Conductive:
Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)Exactly. You said that it conducts electricity in your barrage, NOT that it has capacitive properties. Keep it away from pins and you'll be OK. Conductor=material that permits passage of electrical current. capacitor=electrical component used to store energy ELECTROSTATICALLY. Generally, a little more research and less emphatic expressions would be beneficial. |

I've found that the pair I have run best at 212.5 freq, --queue=1, hashing reliably for 2 days at 428. I'm fairly bummed that it won't reliably do more and won't be buying anymore until they fix the issues with the DC/DC converters.
Hi, I mostly missed the queue discussion, but the gist is that instead of sed -i 's/--queue 4096"/--queue 0 --scan-time 1 --expiry 1"/g' /etc/init.d/cgminer I can/should use sed -i 's/--queue 4096/--queue 1/g' /etc/init.d/cgminer Correct? Thanks. Hmm those double quotes " don't look right in that sed command - paste the contents of /etc/init.d/cgminer... Not a software coder, got it here, but please correct if it is so. You won't need the double quote now since you're just goig to change --queue 4096 with quue 1. What iu are doing is replacing this part at the end of the command: --queue 4096 with --queue 1 To see the line you want to change in the file out can just run a grep to see it: grep "queue" /etc/init.d/cgminer The output will show you the line out will modify with the used command. It will also show you that queue only shows up on that line. So, to be clear this is what you want to enter if you are editing the file from default. Including backing up the original file: cp /etc/init.d/cgminer /etc/init.d/cgminer.bak <press Enter>
sed -i 's/--queue 4096/--queue 1/g' /etc/init.d/cgminer <press Enter> Go to the web interface for the miner config and click save and apply. This will restart cgminer and it will reload the new config. Fantastic! Thanks. |

Quick question. My Antminer on any clock setting seems to run at the expected hashrate for a few hours until eventually dropping off a few hours later. The stock clock drops down to 410 gh/s after a little white and then the overclock speeds drop even further. I do have 4 power connectors attached. Any suggestions?
Make sure you've got the latest firmware. Mine went from 410 to 441 after updating. I've also found that they operate better with two, not four, pci-e connectors and using the connectors at the front (towards the network connection port). how long did you check this for (2 instead of 4 connectors)? |

I have a question on compensation for SP30's. Per note announcing the SP30: http://www.spondoolies-tech.com/blogs/news/14979953-introducing-the-sp30: Compensation will be based on preserving the $/GH ratio of the original deal.
The hash rate spec dropped from 5.4TH/s to 4.5TH/s -- a reduction of 16.7%. Based on this, those of us who paid $5095 are due for a compensation of $5095 * 16.7% = ~$850 -- with the final adjusted price being $5095 - $850 = $4244. Yet, new customers are now charged $3895 for the same product -- which is a significantly higher discount than the one paid by those of us who pre-ordered a while back. So, the question for Spondoolies is: Is 16.7% the final compensation that is coming in October? why exactly you are asking (meekly) if this is what you are going to get instead of requesting fair compensation, which is 25% (4.5 vs 6Th-this is what I ordered) plus compensation for higher electricity use (3000W vs 2500w)? Sheesh. |

The trend is so blindingly obvious that it scarcely warrants mention: unskilled labor gets easier and easier ( hard/dangerous/dirty labor gets paid more), and the wages received buy a dramatically greater standard of living. When we add in technological innovations that further save on the labor that is otherwise necessary for basic living - such as washing dishes, bailing water from a well (to say nothing of digging and maintaining the well) - the argument becomes several times more striking. How does this apply to real estate? In the US a lot of people living in crack addled trailer parks who have iPhones and Netflix, but they still have drug addicts for neighbors. We need to broaden what is included in our "quality of life" stats to capture this; it's presently invisible. What do you think living 200 years ago was like for people of similar skill level, family circumstances, and motivation? Or perhaps I shouldn't say living: the vast majority of them would probably not be living at all. For the last 200 years it is a correct assessment, but if you are old enough, comparing 2014 with 1999 in almost every aspect (except, bitcoin  ): living conditions, income and work load in US for a majority of the population are much worse in 2014, no question about it. Creeping unrecognized inflation; long term unemployment; higher premium, but worse medical plans-we have it all. Because of high unemployment, people have difficulty changing jobs and/or moving, etc., etc. I am trying the Piketty book-it seems that he got something right there regarding the cause of this situation, but I am not sure what solutions (if any) are possible. |

Question to someone adept in thermal paste application:
1. If you take the heat sink off and see that paste is applied OK by Bitmain, can you just slowly plop the heat sink back, or you HAVE to clean up and reapply new paste?
2. How much of AS5 to apply? I tried to do it on the first machine (too early to know the results) and you can actually spread it very thin with a rasor blade or exacto knife.
3. When it stabilizes after the application as far as thermal transmission is concerned? AS5 manual talks about something happening in ~25hr and something else in ~200hr.
1) yes and no. if you dont adjust and reapply some paste it would likely be worse than it started out. might still function fine but after all the work of remounting it you would have poorer contact than you started with 2) small amount. maybe the size of a plastic BB. dont put much effort spreading it since the pressure of the heatsink should do that for you 3) give it at least 12hrs to cure a little before running the antminer, it may take longer to reach 100% cured but will work anyways no need to wait to try to cure the thermal paste since thermal paste does not dry or seal . you can powerup as soon as it is applied. Thanks to everyone who responded. BTW, Arctic Silver 5 has thermal conductivity of ~8.5W/m-K @aztecminer Yes, Arctic Silver 5 manual says that you can start using immediately, but it will decrease the temperatures slowly (break-in over 200hr) I am running 2.5 hours so far after AS5 application and temperature dropped from the initial 43 to 40-41C already. I will wait to report the speed comparison until 12-14 h mark if not later. @allcoinminer Got it re plopping the heat sink back without cleaning and reapplication. However, I did spread it evenly over the surface, but took care not to have any on pins/connectors (because it is slightly capacitive according to manual). I will post pictures later to explain why I decided to spread it (hint-what you described did not work for Bitmain). @klondike_bar thanks for the info regarding possible air bubble if no re-application of paste. decided not to let it cure-too impatient, but started with lower mhz. If you don't have AS5, and can't wait for amazon, grab it (3.5g) at Microcenter-they usually have loads. I ordered some online, but could not wait  |

Has anyone received coupons from Bitmain for Batch 5?
I did not, and initial coupons were only for Batch 1-3. They could still issue coupons later on, but there was no announcement re this. |

Guys: I been testing a few SP10s in a room in my office, normally the temp is 90F degrees because I have 4 of them in a small space. One day it was 100 degrees in there! The end result what the miners worked great, and I am actually moving them to the datacenter today.
Question: What are you thoughts about running this S3 at 80F? 90F? 100F environments? Would they just shut off? I may test today at 80F. The way I make the temps go up or down is to turn on more miners. I have a room for testing, but there is no ventilation in there. Its a big room, but it heats up fast. Would love to hear who is running at what room temperature. I am sure 80F and below is no problem...
up to 85F is no problem for both S2 and S3. |

since there are so many miners here and I want to buy ANTMINER S3 I'll post my question here. Is there a chart of multipool mining profitability in fiat over a long period of time (6-12months)? If not maybe you can tell me from your experience.. I want to know whether the current $1.6/100GH/day is somewhat stable and can be expected to stay that way the coming 6 months. (I'm a newbie regarding mining, so with this miner I can use it for multipools right?  ) I'd take some serious time learning more about bitcoin before you invest a cent. The difficulty changes after every 2016 blocks. Here is a list of the historical increases. https://bitcoinwisdom.com/bitcoin/difficultyIn the last 6 months it has gone from ~3 million to ~19 million. SO NO WAY you will be making anything close to $1.6/100GH/day in 6 months. thanks! I know about bitcoin difficulty and got burned already I'm asking about the other coins since multipools mine the most profitable, which ever coin it happens to be. But there is no "profitability" chart of multipools over such a period of time. I have been mining at multipool.us for several months. I haven't kept detailed records but can tell you that it now spends >95% of the time mining bitcoin directly, not any of the other coins. The way the pool works ensures that any of the more profitable coins will be mined until they are approximately the same profitability as bitcoin, so it effectively destroys its own market. I imagine the other multipools will have roughly the same effect. The only way to beat the multipools is to mine newer coins before they get added to the pools, which is a bit of a gamble and isn't a set-and-forget option which I think is what you are looking for. It is a circular system. You buy equipment to mine, it increases the network hash rates, so they increase the difficulty, forcing you to buy more equipment to stay profitable, all the new equipment causes them to step up the difficulty again, and make you buy more equipment again. Basically you are spending all your profits on more equipment to stay as profitable as when you started mining months earlier. All in all, the only ones making money are the equipment manufacturers and the power companies. The network hash rates is growing so fast now that you can't make enough profits to invest in solar/wind power to offset the power costs. Once you get into the loop, it is hard to just shut down $20-30K of mining equipment that has only allowed you to buy more mining equipment. Nothing in your pocket to speak of. Kinda sucks unless you have hundreds of thousands invested in equipment already. What prevents you from mining with a couple Th at home, for which you would pay only ~2K. Nobody said that you are supposed to make a living out of it. To me, it is interesting and feels like a contribution to bitcoin success in some way |

All chips are basically overclocked to the max at the moment to get a high hashrate.
Future software versions might achieve a small increase, but I guess Zvi has tried out a lot of overclocking and the firmware basically sets the speed for each chip independantly.
Could you say something about your datacenter cooling? Are you using evaporative cooling?
I am pretty sure that the SW is making decisions in rather optimal way. We are 99.8% ASIC work time, 0.1% HW errors, <0.5% idle shares. The only place I can theoretically improve is in decision making about how I distribute the power, but I don't think there is more then 1%-3% there. I hope I am wrong, we will continue to investigate of course, but I would say this is probably what those ASICs provide for this power. Regarding cooling, the slow corner is rather insensitive to heat, and we have a lot of spare power in DC2DC (unlike SP10 April/March batch), so it will not have big impact - maybe 1%. Note that 100GH sounds like a big difference, but it is just 2.5% of SP30. Just for 0.5% idle shares you loose 20GH on SP30. So, you are holding the fort today and Guy is resting after the marathon past midnight session? Q1: Guy was saying something about slightly faster wafers. Would these be in time for Early september batch? Q2: Now, with chips delivered, is there a timeline for when early September batch would be delivered (to US)? Some hosting sites have a very precise schedule. |

Its interesting reading all the posts with everyone micro analysing. I decided to buy a few bitcoins about a month back when the price was 580 and seen a price rise to 640'ish then a slow decline back to 580 Let me share my thoughts from a real Newbie perspective. All the news I am reading is reinforcing that bitcoin is here to stay BUT this only applies if you are already a Bitcoin convert. Try looking at the news from an outsiders perspective and then you will soon realise there is nothing YET which will attract a mad rush. In fact, the news is probably negative from their perspective as its all about regulation and seen as uncertain doom and gloom. How is New York looking to overregulate the crap out of it making it almost impossible to trade be good news!! The counter arguement is simple; Bitcoin doesn't need New York it just needs financially credible locations and solid support to evolve. Just to give you a small example i read a post from a major financial journal on bitcoin clearly stating that it was a shame the industry hadn't made it 3rd world friendly as over 3 billion people are impoverished and have no access to bank accounts etc. Shame he didn't take time to do some research www.37coins.comMy position is simple.. Keep reading the news as it dribbles through and each day ask myself.. is this adding to the foundation and strengthening Bitcoin. Soon a major incident will break.. maybe a Warren Buffet or an Ebay and it will pump to $2500 and then, have a guess what. the same scenario will happen all over again as it drops back to $1500 BUT your portfolio will still have increased THREEFOLD! From a simpleton newbie perspective. Just want to know if the price will hit 100k some day. No, unless world would go through some kind of ordeal, which would suck for most people. Mammals were small furry animals, mostly the size of mice. A large asteroid hit Earth 65 mil years ago, dinosaurs died off and mammals became the dominant animal group. Bitcoin would take a very long time, if ever, to replace the current banking/money system without banking crash. |

@Biodom
It is when you go in to your my choice account and go to Change Delivery. You can have them Hold for pickup. So for me who ever did it new they were only 4 Antminers at the local warehouse even before I did.
I don't want to point fingers, but don't you need a password to do this? "friend" or "estrange gilrlfriend" looks likelier than a random UPS guy. Just saying.... |

Basically the co. over promised and under delivered, this is not the way to do business and is the reason why I will never buy a Pre-Sale, I bet the co. knew there would be issues with hardware hence no refund. Currently I only buy from companies that sell from stock, When Spondoolies sells from stock is the day I place an order.
What are you talking about? they were selling SP-10 from stock for quite a while. |

For customers receiving units before October, we will adjust the price of your machines consistent with the 4.5TH/s +- 5% hash rate. Compensation will be based on preserving the $/GH ratio of the original deal. Starting in October, we will compensate you for the differential in hashing power according to each customer's preference. We will contact each and every one of you over the next few weeks to discuss your preferred method of compensation.
Early thoughts likely to be amended.... Whilst I appreciate that you will compensate buyers, $/GH isn't the only factor. They've gone from 0.4w/GH to 0.67w/GH which significantly impacts both the running costs AND the length of time these will be viable to run. Yes, this is did not receive any mention in the original statement. I am at a loss, however, at the 0.55W/Gh number that was a secondary comment. If it is 0.55W/GH for 4500GH, then it is 2475W, which is exactly what was expected. Confused as to where the 3kw number is coming from. July-September batches: 4500GHs +- 5% with 3000 Watt at the wall October and later batches: 5500GHs +- 5% with 3000 Watt at the wall OK, great. Then, the 0.55Gh/w is at the instrument level? From the point of view of consumer, it is 0.67W/Gh because I am getting 4.5TH and pay for 3kw to my power provider. I am just trying to see where the numbers are coming from. |

Yes, I will get my July sp30 in the next days.
I am obviously not immune in my desire to speculate, as any naturally curious person isnīt.
OK, then. We can make a poll as to what TH Sp-30 will be at: In my opinion 4-4.5Th. If it is at 3-3.5 th-then it is a shocker. Hit the top value of my range. Not bad at all. 3kw-they probably had to scramble for a new PSU (1600W). 0.67W/Gh-slightly better than S3, slightly worse than KnC Same PSUs. 1200W is the input. It can goes up to 1350W input. At the wall it's 1500W per PSU When downclocking the efficiency is sub 0.55 W/GHs With October batch, the efficiency will be sub 0.55 W/GHs without downclocking Guy I am not a EE, so you lost me there a bit. Anyway, 1500W at the wall means that typical 15A NA circuits are not usable (current of 13.6A which is higher than 12A rating), have to use 20A/110V or 220/240V. Not a tragedy. EEs please comment on how a 1200W supply can provide the 1500W of power. |
